  • Not sure it is what you want. Since we are talking urban water supply, I add urban popultion bu I think it should be removed. The pink arrow – which is changes of access right will have a great impact on the direct use value for local communities living next to reservoir and to downstream communities (water regime according to irrigation needs for example)… Grey arrow, meaning +/- impact on the value because in some case it can have + impact (development of irrigation, cage culture in reservoir etc…) and some case – impact less water, no irrigation etc…

    1. 1. THE CGIAR CHALLENGE PROGRAM ON WATER AND FOOD - MEKONG BASIN DEVELOPMENT CHALLENGE <ul><li>Started in mid 2010, continues to 2013 </li></ul><ul><li>Total program budget around US$5 million ++ </li></ul><ul><li>Aims to reduce poverty and foster development through management of water for multiple uses in large dams and reservoirs </li></ul><ul><li>Six coordinated research projects: </li></ul><ul><ul><li>MK1 on Livelihoods (Site Level) led by IWMI </li></ul></ul><ul><ul><li>MK2 on Water Valuation (Site/Provincial Level) led by WorldFish </li></ul></ul><ul><ul><li>MK3 on Cascade of Reservoir (Catchment Level) led by ICEM </li></ul></ul><ul><ul><li>MK4 on Water Governance led by AIT/MPower </li></ul></ul><ul><ul><li>MK5 on Program Coordination and Communication </li></ul></ul><ul><ul><li>MK6 on Multi Stakeholder Platform </li></ul></ul><ul><li>Working in three countries: </li></ul><ul><ul><li>Cambodia – Sesan/Srepok catchments </li></ul></ul><ul><ul><li>Laos – Nam Theun Himboeun catchment </li></ul></ul><ul><ul><li>Vietnam – Sesan catchment </li></ul></ul>

    4. 4. Mekong Project 2: Water Valuation (MK2) <ul><li>Overall Project Objective: </li></ul><ul><li>Assess the value of water in its various uses and estimate costs and benefits associated with different water management strategies </li></ul><ul><li>Research Questions : </li></ul><ul><ul><li>1) What is the value of multiple uses of water compared to a sector focus on hydropower or irrigation? </li></ul></ul><ul><ul><li>2) Can we balance the value of water being used for alternative purposes, while sustaining the value of water for hydropower? </li></ul></ul>
    5. 5. <ul><li>Total value of water multi-uses estimated in the 3 case study areas </li></ul><ul><li>Integrated water valuation framework developed and field-tested </li></ul>Mekong Project 2 : Outputs Project Team: The WorldFish Center; International Center for Environmental Management (ICEM); International Food Policy Research Institute (IFPRI); Culture and Environment Preservation Association (CEPA), Cambodia; Department of Livestock and Fisheries (DLF), Lao PDR; Central Institute for Economic Management (CIEM), Vietnam

Adapted from Springate-Baginski et al. 2009 <ul><li>Human Impact </li></ul><ul><li>Coping strategies and adaptation: over harvesting; change in land use etc.. </li></ul>
